    Non-uniform load distribution on gear teeth occurs due to misalignment of gear and pinion shafts or due to inaccuracies in tooth profile during meshing. The ends of tooth are made thinner to obtain a barrel shape along the flank in order to minimize excessive load on tooth ends. This process is usually called as crowning of gear tooth.
    Excessive backlash effect causes nonuniform transmission of motion. To avoid integer number as gear ratio an extra tooth is added called as hunting tooth.
